I am stuck on a section of a Flintstones multigriddler, and I hope someone can help me figure it out. I've tried several different combinations, but I can't find anything that fully fits. The puzzle number is 76571; the screen shot is only part of the puzzle, but it should have enough of the clues. Any suggestions?

Actually, you should have given the whole picture...When you get to the point, that you show in your screenshot, you have already used the black clues in column 4&5 (rows 6-8), right? That leaves only one place for the 4 in row 21 (columns 24-27) and then you can solve row 25. Should be easy after that.
